undefined reference to `_gmtime32' with boost threads tutorial - c++

Question

I was following this beginner tutorial on boost threads:
http://www.codeproject.com/Articles/279053/How-to-get-started-using-Boost-threads
Everything was going fine with this sample they provided:
#define BOOST_THREAD_USE_LIB
#include <iostream>
#include <boost/thread.hpp>
#include <boost/date_time.hpp>
void workerFunc()
{
boost::posix_time::seconds workTime(3);
std::cout << "Worker: running" << std::endl;
// Pretend to do something useful...
boost::this_thread::sleep(workTime);
std::cout << "Worker: finished" << std::endl;
}
int main(int argc, char* argv[])
{
std::cout << "main: startup" << std::endl;
boost::thread workerThread(workerFunc);
std::cout << "main: waiting for thread" << std::endl;
workerThread.join();
std::cout << "main: done" << std::endl;
return 0;
}
But then I decided to try it without the sleep function. So I commented out those lines.
#define BOOST_THREAD_USE_LIB
#include <iostream>
#include <boost/thread.hpp>
#include <boost/date_time.hpp>
void workerFunc()
{
//boost::posix_time::seconds workTime(3);
std::cout << "Worker: running" << std::endl;
// Pretend to do something useful...
//boost::this_thread::sleep(workTime);
std::cout << "Worker: finished" << std::endl;
}
int main(int argc, char* argv[])
{
std::cout << "main: startup" << std::endl;
boost::thread workerThread(workerFunc);
std::cout << "main: waiting for thread" << std::endl;
workerThread.join();
std::cout << "main: done" << std::endl;
return 0;
}
I started to get the following compile error:
)]+0x40)||undefined reference to `_gmtime32'|
I've done quite a bit of snooping around trying to figure out what this means and why it is only happening when I remove those two lines. As of right now, I am leaning towards it being something to do with some kind of header, like time.h, that I have to include (although I tried that already obviously).
I am using a rather strange setup. Code::Blocks with mingw/gcc. I compiled the boost library myself with command line arguments following the codeblocks tutorial:
http://wiki.codeblocks.org/index.php?title=BoostWindowsQuickRef
Everything seemed to work fine with this, but I suppose I could have built the libraries incorrectly.
I would dig deeper but the file name of the error is not standard and is listed as ")]+0x40)". I am not sure what this means - is it maybe some kind of file location address?

I think the error is on this line of c_time.hpp:
static std::tm* gmtime(const std::time_t* t, std::tm* result)
